This is to announce the availability of VRML-modules.  This is still an
beta release.  I have only used it in small, toy applications, like
Netscape Bookmark File to VRML converter or thesaurus visualisation, 
(http://www.gfz-potsdam.de/drz/VRML/bmvrml.html) so there
are probably bugs in it.  Still, it does seem to work well in the cases
I've tested it in, so others may find it useful, and at this point, I
would
like to get some feedback about it.

VRML is a module for dealing with VRML nodes. It is object oriented and 
has some added functionality with respect to VRML plugins.
- uses X11(Netscapes) color names
- compact format: $vrml->cube(3,"yellow")
- usefull for dynamic VRML generation with CGIs and HTTP-Server
- respects HTML-Browser, VRML-Viewer, FRAMES
- creates VRML 1.0c or VRML 2.0 with the same script

Modules in the VRML package:

VRML
VRML::VRNL1
VRML::VRML1::Standard
VRML::VRML2
VRML::VRML2::Standard
VRML::Color
VRML::Basic

This module is available from CPAN and also from my home page:

Example:

use VRML;
VRML->new->browser("LIVE3D")
->background("black", "starbak.gif")
->cube(2,"orange")->print;

*** generate VRML 1.0c ***

#VRML V1.0 ascii

# Set Browser to: 'LIVE3D'
DEF BackgroundColor Info {
        string  "0 0 0" # black
}
DEF BackgroundImage Info {
        string  "starbak.gif"
}
Group {
        Material {
                diffuseColor    1 0.647058823529412 0   # orange
        }
        Cube {
                width   2
                height  2
                depth   2
        }
}

*** or VRML 2.0 ***

#VRML V2.0 utf8

# Set Browser to: 'LIVE3D'
Background {
        backUrl "starbak.gif"
        bottomUrl       "starbak.gif"
        topUrl          "starbak.gif"
        leftUrl         "starbak.gif"
        rightUrl        "starbak.gif"
        frontUrl        "starbak.gif"
        skyColor        0 0 0
}
